APPARATUS FOR HEATING AND VENTILATING ROOMS.

SPECIFICATION forming part of Letters Patent No. 464,698, dated December8, 1891.

Application filed January 14, 1891. Serial No. 377,759. (No model.)

To aZZ whom it may concern:

Be it known that I,WAL1 EMAR TARP, a citizen of the United States,residing in the city and county of San Francisco, State of California,have invented certain new and useful Improvements in Apparatus forHeating and Ventilating Rooms, of which the following is aspecification.

My invention relates to improvements in heating and ventilatingapparatus for houses; and it consists in the construction andarrangement of passages and dampers, hereinafter described, and pointedout in the claims.

The following description explains the nature of my said invention andthe mannerin which I proceed to construct and carry out the same, theaccompanying drawings, that form part of this specification, beingreferred to by letters.

Figure 1 represents the front of achimney projecting into the room of abuilding from the floor-line up to or nearly to the ceiling, and withthe front face on each side of the fire-place broken away to show thearrangement of the air-passages. Fig. 2 is a vertical section throughFig. 1 at about the line at 00. Fig. 3 is a horizontal cross-sectiontaken through Fig. 1 at the line-cc y.

It will be seen that the heating-chamber A and the cold-air fiues orpassages are best formed at the time of building the chimney; but theapparatus can be applied for operation in chimneys already built bytaking down the front walland rebuilding it.

The chamber A is constructed, preferably of sheet metal, by fixing apartition or back plate across a flue back of the chimney-breast, and acorrugated plate is used to increase the amount of heating-surface.Suitable space is left between this corrugated back and the back wall ofthe flue for free passage of the smoke and gases from the fire below.

X is the breast of the chimney, A A the top and bottom plates of thechamber, and A the back plate, while A indicates the inclosedair-heating space.

13 is a passage through the front Wall opening into the room, and Bis adamper or register to reduce the opening or to close it at pleasure.

O C are air fines or passages formed in the brick-work on either side ofthe chimney, with mouths c at the bottom opening into the room, andopenings 0 at the top communicating with the heating-chamber. One ofthese passages may be arranged on each side of the fire-place, as shownin Figs. 1 and 3, and where the chimney sets forward into the room thelower ends of the passages are carried outat the sides. will permit thisto be done, however, the out lets can be placed at the front. A singlepassage at one side of the fire-place can also be used instead of thetwo passages represented in the drawings.

In cases where the construction D is a fresh-air flue or passage runningfrom the outside through the back of the chimney into the passage C, andprovided with a slide valve or damper D, arranged to be worked 7 fromthe inside of the room. Through this passage fresh air is supplied inquantity as required from time to time, or an outlet from the room tothe outer atmosphere for the vitiated air is furnished.

By the arrangement of double passages represented in the drawings acirculation of warmed air from the heater can be maintained by openingboth or either of the dampers D and (3* on both sides of thechimney-breast, and by suitable adjustment of the dampers an outwardflow of vitiated air from the room through the passages to the outer aircan be produced, fresh air entering through one passage D and the warmair discharging to the outside through the opposite passage D. in whichcase the dampers 0* and D on one side are closed while those on theother side are open.

As thus constructed and arranged my improved apparatus will heat andventilate a room with considerable economy of fuel, as it can bearranged to utilize the waste heat from one fire for warming the air ofa sepa rate apartment.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

l. The combination, with a chimney, of horizontal passages D, extendingto the outside atmosphere and having dampers D, operated from theinterior of the room, and dampers 0* ICO inside the dampers D, openinginto the room,

passages 0, extending upward from the passages D, and an inclosed box Ain the chimney communicating with the passages G and with opening 13into the room, as set forth.

2. In a heating" and ventilating apparatus,

into said chamber and an opening therefrom into the room, as set forth.[0

In testimony that I claim the foregoing I the combination, with achimney; of the corhave hereunto set my hand and seal.
